This is the largest digging machine in the world. The bucket-wheeler excavator is called Bagger 288 or Excavator 288, built by Krupp of Germany. This thing’s over 300 feet high, more than 700 feet long machine and is the largest land vehicle in the world at 13,500 tons:

The Crawler-Transporter is a tracked vehicle used to transport such enormous objects as the Saturn V rocket and the Space Shuttle. These were the largest tracked vehicles in the world until they were overtaken by the Bagger 288 excavator:

The F60 is apparently the world’s largest machine that can move. The cutting height is 60 meters, hence the name and at 502 meters long, this has been called the ‘lying Eiffel Tower’. This machinery is used in Germany for brown coal or lignite opencast mining:

This is the world’s biggest tunnel boring machine – 400 feet long, 51 feet in diameter and weighing 9.5 million pounds (left image below). The tunnel machine on the right was used to construct underground sections of the transit lines in Toronto:

The monstrous Liebherr T 282B is a large earth-hauling dump truck designed in Germany in 2004. It became the biggest earth-hauling truck in the world, with the most advanced model driven by a 10.5 ton, 3650 hp, 90 liter diesel engine:

This colossal machine called The Captain was built in 1965 and was the world’s largest power shovel, until it was scrapped in 1992. The bucket could hold 300 tons of material and at 28 million lbs this was the heaviest land vehicle ever built and one of the two largest land-based mobile machines ever constructed:

The Bucyrus-Erie 1850B, built in 1962 at a cost of $6.5 million, is also known as Big Brutus, and it certainly is big. 160 feet tall and weighing 11 million lbs, the bucket could carry 150 tons of material and not surprisingly the machine had a maximum speed of just 0.22 mph. This machine isn’t the largest electric shovel ever built, but it is the largest electric shovel still in existence. Big Brutus was in operation in the sixties and seventies and is now on display at a mining museum in West Mineral, Kansas:

The Big Bud 747 or 16-V 747 is the world’s largest farm tractor, weighing 100,000 lbs. This agricultural monster is 27 feet long, 20 feet wide and 14 feet high. It only travels at 8 mph, but is capable of cultivating 60 acres in an hour:

And finally, here’s the Large Hadron Collider (LHC), the biggest and highest-energy particle accelerator in the world, designed to collide opposing particle beams. Constructed by the European Organization for Nuclear Research (CERN) and involving 10,000 engineers and scientists from universities and laboratories in more than 100 countries, the Collider is located underground on the France-Switzerland border near Geneva.
